Abstract
The utility model relates to a four-way directional control ball valve for a heat accumulating type burner. The ball valve comprises a valve body, a valve ball, a valve seat, a valve rod, a joint, etc. The valve ball is opened with two L-shaped passages, the ball valve is provided with four interfaces (A, B, C, D). When the valve ball is in the state as shown in the figure, An is communicated with B, and C is communicated with D. after the valve rod drives the valve ball to rotate an angle of 90 degrees, An is communicated with D, and C is communicated with D; the directional control requirement of the heat accumulating type burner can be met. The utility model adopts the spherical surface sealing, the sealing clearance can be conveniently adjusted, and the sealing performance is reliable; the four-way directional control ball valve for heat accumulating type burner solves the problem that the rate of the air leakage of a heat accumulating type directional control ball valve is high; also the four-way directional control ball valve for the heat accumulating type burner has compact structure and long service life.
Description
Technical field
The utility model relates to a kind of required commutating device of burner that adopts regenerative combustion technology or HTAC.
Background technique
In the prior art, the used four-way change-over valve great majority of heat-accumulating burner that disperse commutation control are to adopt the rotating plate type spool, and its sealing reliability can be poor, has the high problem of air leak rate of air curtain, influenced burning quality to a great extent.In order to solve the problem of leaking out of disperseing four-way change-over valve in the reversing control system, two three-way valve of normal at present employing are used in combination the function that replaces a four-way valve, and require two three-way valve synchronization motions, have increased the quantity and the control difficulty of actuator like this.
Summary of the invention
The utility model purpose is to provide a kind of four way ball valve reliable, simple in structure that seals, to solve the problem of leaking out of disperseing four-way change-over valve in the reversing control system.
A kind of heat-accumulating burner is made up of valve rod 1, gland 2, end cap 3, socket head screw 4, Sealing 5, adjustment spacer ring 6, joint 7, pad 8, valve seat 9, valve ball 10, valve body 11, packing ring 12, bolt 13 with four-way commutation ball valve four-way change-over valve, it is characterized in that valve ball 10 adopts ball face sealing, has two " L " type passages on the valve ball.
Form the axially locating form of the valve seat 9 of sealing surfaces with valve ball 10, carry out axially locating by 7 pairs of valve seats of joint, each valve seat can be adjusted the matching gap between each valve seat and the valve ball separately independently by dismounting.
Adopt the four-way change-over valve of ball face sealing, its sealing is reliable, simple in structure, is specially adapted to disperse the heat-accumulating burner that commutates and control.
Description of drawings
Fig. 1 is a four-way commutation ball valve plan view.
Fig. 2 is a four-way commutation ball valve plan view.
Four-way commutation ball valve is made up of valve rod 1, gland 2, end cap 3, socket head screw 4, Sealing 5, adjustment spacer ring 6, joint 7, pad 8, valve seat 9, valve ball 10, valve body 11, packing ring 12, bolt 13.
Embodiment
The axle head that goes out of valve rod is processed into outer four directions (or external splines) and directly is connected with pneumatic (or electronic) final controlling element, drives valve rod by final controlling element and rotates, and valve rod drives valve ball, realizes 90 ° of back and forth rotations of valve ball.In regenerative combustion system, interface of four-way valve is connected to air pipe line, and the interface on its opposite is connected to exhaust pipe, and all the other two interfaces are connected respectively on the interface of heat-accumulating burner of this valve control.Selector valve just can be controlled the alternately commutation of the air and the waste gas of corresponding burner like this.
Claims (2)
